I Application filed lay 27, 1907. Serial No. 375,928.

To all whom 'it 'may concern.'

l wmcnu HECK, a. citizen ofthe United States, residing at Findlay, inthe countv of. Hancock.` 5 and StateofK Ohio, have invented certain-new.

and useful Improvements in dSectional Con'- veyer'- Frames for Excavating 1Vleohines; andl do hereby declare thefollowing to be e full,` clear,.andexact descri tion of the invenl0,

art to which it' appertains to make and use the same. This invention relates to conveyors for excavating `machines, and is particularly designed for use with ditchingr machines providing a.- large revoluble hollow ditching Wheel withinuwhichisv located, a transversely-disposed conveyer for carrying the dirt projected thereon, by the buckets of the ditching y Wheel, transversely of the ditch being out. And it is very desirable in a machine of this character to provide seid transverse conveyor insome 'way with suitable means for elevatingauddowering the frame to Ineke the dis-- charge end assume different angles 'of position for various purposes, for instance in orderto allow the outer end of the conveyor to be kept from interfering with the waste benk, also to allow the part under end .Within the Wheel to remain .stationery and level. for the discharge of dirt thereon. It may also he serviceable in avoidingl obstructions niet with .in the digging ci a ditch across rough ground. ln conveyors es et present employed, the conveying'apron, where adjusteb y supported et ell, carried by rigid freine pivotslly connected to the framework oi the excavating meshine, the entire conveyor frame swii ing on its pivot, s'. construction which me been found to he more or less disadvantegeous, and one of the objects ol the resent invention is to provide the trarne fortne con- "tfeying apron inthe form lof a sectional freine, the sections of which are iivotally secured together, and one section heing adapted to he rigidly secured to the mac of the conveyor being adapted to be raised or lowered, es occasion may require. At the seine time these sections are provided with suitable s rocket 'wheels and rollers coperating with sprocket chains secured to the apron, 'and so yreleted that when the movable ofthe frame not in a straight position tlmapron will stillfreely move, although one prort-ion of the same is Be it known that I, ANDERSON. CART-n vvide what I have termed ceivingend or stationany` pat o the conveyor ,such1 as canvas or similar strips, disposed to project Ain engagement tion,.such as Will enable ot ers skilled in the Fig. 3 is a cross section hine, the remainder at'a different angle om the other.
